ADJUSTABLE HAM E.

SPECIFICATIdN forming part of Letters Patent No. 424,407, dated March 25, 1890.

Application filed December 16 1889. Serial No. 333,885. (No model.)

To all-whom it may concern.-

Be it known that I, ADOLPHUS V. CRONK, a citizen of the United States, residing at 0rd, in the county of Valley and State of Nebraska, have invented certain new and useful Improvements in Adjustable Hames; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain novel features involved in the construction of hames for harness, the object being to produce an adjustable hame that can be readily made to conform to various sizes of collars used without losing in any degree its efficiency. This result I secure by means of the construction described in the following specification, and illustrated in the accompanying drawings, in which similar letters of reference designate corresponding parts in all the views.

Figure 1 is a perspective view of myinvention as applied to use. Fig. 2 is a longitudinal section of Fig. 1 on a line with X X. Fig. 3 is a transverse section of Fig. 1 on a line with Y Y. Fig. 411s a perspective view of the tug-adjusting attachment separated from the hame.

Designating the several parts by letter, A is the hame proper formed in the usual manner, except that it is provided longitudinally on its upper end and front side with a deeply-cut groove a, the upper end of which terminates in a transverse slot a, intended, re spectively, to provide abed for screw-threaded shaft B and operating milled head I), as will a be hereinafter described.

In order to provide a means for connecting the upper ends of the hames I arrange collar O, which is constructed to snugly fit around the end of said hame, while the inner end thereof is provided with the projection c, to which is secured the strap making the 0011- nection. The collar 0 is provided with the inwardly-reaching guide 0', which is made to fit into the groove a, and is provided with a screw-threaded hole for engaging with the threaded shaft B, and it will be seen that when said shaft is caused to rotate by means of the operating milled head b on the upper end of same it will cause the collar C to slide up or down upon the hame, as may be desired by the operator, and thus practically lengthen or shorten the reach of the hame. The shaft B is properly secured within the longitudinal groove a, so that a rotating movement can be readily given it by means of the milled head I), which projects sufficiently past the surface of the hame to enable the operator to rotate the same as desired. In like manner I provide an adjustable device for that part of the hame connected to the tug. I efiect this means by providing the clip D, arranged to be secured to the front side of the hame or to be embedded therein and secured by the beveled ends thereof, as shown. Said clip is provided with the longitudinal slot (1 and transverse slot d ,intended, respectively, to provide a bed for the screw-threaded shaft E and the operating milled head e on the upper end of same, as shown. Arranged to move up or down upon shaft E is the guide F, so

constructed that it will snugly fit within the slot (Z, and provided on its inner-side with a screw-threaded opening arranged to be engaged by shaft E, as shown, and itwill be seen that said guide can be readily caused to assume any position desired within said groove by turning to the right or left the operating milled head 6, as will be readily understood. To the outer projecting end of guide F and the rearward side of same is secured the staple f, which is intended to form a connection with the tug. It will be'seen from the above description, when it is desired to shorten the hame so that it will fit the smallest collar, the collar 0 is caused to follow the shaft 13 downward. until the lower end of same is reached, and in like manner when it is desired to have the longest possible length of hame said collar will follow said shaft until the upper end thereof is reached. In like manner the point of attachment for the tug can be varied as desired.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination of the hame'having a longitudinal groove, the shaft mounted in said groove, and the collar fitting around the hame, provided with a guide 0, entering the groove and engaging the shaft and having a projection c, as set forth.

2. The combination, with the hame having a longitudinal groove near its upper end, of

the shaft mounted in said groove, the collar 1 fitting on the upper end of the haine, provided'with a projection c and having a guide engaging the shaft, the clip secured to the lower portion of the hame and having a 10ngitudinal slot, the shaft mounted in said slot, and the guide fitting in said slot and engaging the shaft and provided with a rearwardlyprojecting staple, as set forth. 5 10 In testimony whereof I affix my signature in presence of two Witnesses.

ADOLPHUS V. CRONK.
